Abstract

Acyloxyphenyl derivatives of oxazolone, which have tree photo active centers, were synthesized and their physicochemical properties are determined by NMR, absorption, fluorescence excitation and emission spectroscopies. The semi-empirical calculations carried out according with the theory of the PM3/CI level has shown, that at an irradiating of their solutions by UV-light give no possibilities of the photo-Fries reaction. The calculated values are in a good accordance with the experimental ones..

Keywords
